The Brewing
Process
Brewing is the actual process of alcoholic beverages and
alcohol through fermentation. This method is used with beer
production, although the term can also be used for other drinks
as well. The term
brewing is also used to refer to any chemical mixing process as
well.
The process of brewing has a long history indeed, which
archeological evidence tells us that this technique was
actually used in ancient Egypt as well. Many descriptions of
various beer recipes can be found in Sumerian writings, which
are some of the oldest writings of any type.
Even though the process of brewing is complex and varies
greatly, Below, you'll find the basic stages relating to
brewing.
- Mashing - This is the first phase of
brewing, in which the malted grains are crushed and soaked
in warm water in order to create an extract of the malt.
The mash is then held at constant temperature long enough
for the enzymes to convert starches into fermentable
sugar.
- Sparging - At this stage, water is
filtered through the mash to dissolve all of the sugars.
The darker, sugar heavy liquid is known as the wort.
- Boiling - The wort is boiled along
with any remaining ingredients to remove any excess water
and kill any type of microorganisms. The hops, either whole
or extract are added at some point during this stage.
- Fermentation - The yeast is now added
and the beer is left to ferment. After it has fermented,
the beer may be allowed to ferment again, which will allow
further settling of the yeast and other particulate matter
which may have been introduced earlier in the process.
- Packaging - At the final stage, the
beer will contain alcohol, but not too much carbon dioxide.
The brewer will have a few options to increase the levels
of carbon dioxide. The most common approach is force
carbonation, via the direct addition of CO2 gas to the keg
or bottle.
After it has been brewed, the beer in normally a finished
product. At this point, the beer is kegged, casked, bottled, or
canned. Beers that
are unfiltered may be stored for further fermentation in
conditioning tanks, casks, or bottles to allow smoothing of
harsh alcohol or heavy hops.
There are some beer enthusiasts that consider a long
conditioning period attractive for various strong beers such as
Barley and wines. Depending on the beer enthusiast and what he
likes to drink, it will vary.
